SAW SET AND ADJUSTING GAGE.

Specification of Letters Patent.

Application filed July 8, 1911.

To (Ml whom it may concern:

Be it known that I, LoUIs VASHAW, a citizen of the United States, residing at Bergland, in the county of Ontonagon and State of Michigan, have invented certain new and useful Improvements in Saw Sets and Adjusting Gages, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in combined saw sets and gages, and the invention has for its primary object a simple, durable and eflicient construct-ion of device of this character, which will be found convenient to hold in the operators hand and the parts of which may be easily constructed and readily assembled and disassembled.

The invention has for a further object an improved device of this character embodying an anvil bar which projects laterally on both sides of the main body portion of the device and which is provided in its projecting ends with apertures in which screws are adjustably mounted, whereby said screws may be projected more or less from the front face of the anvil bar for gaging purposes, or, if desired, to be adjusted from one aperture to another, so that they may be used as positioning elements to assist in holding the device firm as against displacement longitudinally of the saw blade being operated upon, as will be hereinafter more fully set forth. And the invention also aims to generally improve devices of this class and to render them more useful and commercially desirable.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which, I V

Figure 1 is a front elevation of the device, Fig. 2 is a side elevation thereof, and, Fig. 3 is a partial section and partial side elevation of the device, the section being taken approximately on the plane indicated by the line 3-3, of Fig. 1.

Referring to the drawings, the numeral 1 designates the body portion of my device, the fr nt face of which is substantially flat -with the lower portion 2 thereof protruded forwardly beyond the upper portion 3, and the rear edge of the body portion 1 is preferably rounded or convex, as indicated at 4, whereby it may be easily held in the operators hand.

At the juncture of the lower and upper portions 2 and 3 of the front face of the body portion 1, the same is formed with a transversely tapering dovetailed slot 5 extending from one side of the body portion to the other, the upper and lower dovetailed walls of said recess being indicated at 6. An anvil supporting bar 7 is adapted to he slipped by an endwise movement into the dovetailed recess 5, the intermediate portion of said bar being tapered and beveled to conform to the dovetailed tapered recess 5, whereby the said bar may be easily slipped into place and held firmly in the body portion 1 by frictional engagement therewith and easily removed from the body portion whenever desired for the purposes of repair or the like. The front face of the bar 7 lies flush with the lower portion 2 of the front face of the body portion 1, and is solidly supported at its middle portion where it is formed on its upper edge, with an anvil 8, the front face of which is beveled in the usual manner, as clearly illustrated in Figs. 2 and 3. Preferably, the ends of the anvil 8 terminate short of the ends of the bar 7, of

which the anvil forms a part.

Preferably, the ends of the bar 7 project laterally beyond the side faces of the body portion 1 and each of said projecting ends is formed with a plural number of apertures 9 extending therethrough, said apertures being threaded, and screws 10 Working in the said threaded apertures and being shiftable from one aperture to another. These screws are not only for gaging purposes, but are also provided for the purpose of assisting in holding the device as against accidental displacement. In certain forms of saws wherein the teeth are relatively elongated and spaced apart, it is evident that the screws 10 may be adjusted to such positions that their forward ends will project between the teeth and prevent any accidental displacement of the setting device and gage as the teeth are hammered against the anvil 8. The upper portion 3 of the front face of the body portion 1 is formed with the usual threaded socket 11 for a gaging screw 12.

From the foregoing description in connection with the accompanying drawings, the operation of my improved device will be apparent. In the usual operation of the device, the screws 10 are turned until the forward ends thereof do not project beyond the front face of the anvil bar 7 whereupon the device is applied to the teeth of a saw so that the front face of the bar 7 rests against one face of the saw. The device is held in one hand of the operator and the hammer or other tool is grasped in the operators other hand and the teeth are hammered against the anvil 8 to the proper angle. After the teeth have thus been hammered and it is desired to know whether or not they have been disposed at the proper set or angle, the device is moved vertically downward until the outer face of the gaging screw 12 is brought into horizontal alinement with the points of the teeth, it being understood that this screw has been adjusted to project a predetermined distance beyond the portion 3 of the front face of the body portion 1. If the teeth do not contact with the gage screw 12, the teeth have notbeen properly set and require further hammering, and in this manner, the exact set of each tooth may be obtained. teeth of the saw to a greater angle than that of the beveled front face of the anvil 8, the screws 10 may be turned so that their free ends project a short distance beyond the front face of the bar 7, whereupon, as is Should it be desired to set the manifest, they will impinge against the face of the saw and the teeth hammered against the beveled front face of the anvil will, be disposed at a greater angle than previously. In certain forms of saws wherein the teeth are of the elongated type and spaced apart, the screws 10 may be allowed to remain in such position that their forward ends will project beyond the front face of the bar 7, and hence, when the device is applied against the saw, said projecting ends of the screws will fit within the spaces between the teeth and prevent any displacement of the device longitudinally of the saw blade, as the teeth are hammered against the anvil.

What I claim is A device of the character described, including a body portion, an anvil bar carried thereby and provided with an anvil, the ends of said bar projecting laterally beyond the side faces of the body portion and each of said ends formed with a plural number of apertures extending therethrough transversely of the bar, and combined gaging and positioning elements adjustably mounted in any of said apertures, for the purpose specified.

In testimony whereof I hereunto atlix my signature in the presence of two witnesses.
